How to calculate hexadecimal.

Question

I know what hexadecimal is, but I don't know how to turn a number into it or turn it into a number.

Answer 1

Note: made it beginner friendly

In hexadecimal, numbers go from 0-F.

0 = 0
1 = 1
....
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15

---

If a number gets greater than 15, like 16, add 1 to the position next to the current hexadecimal position and make the current position be 0.

Hex. = Dec.
F = 15
+ 1 = 1
-------------
10 = 16

If a number is over 256, like 257, the same process happens:

FF = 256
+ 1 = 1
------------------
100 = 257

Hope it helps 😃
